IMPROVMENT IN BUNGS.

Specification forming part of Letters Patent No. 150,379, dated April28, 1874; application filed February 28, 1874.

To all whom tt may concern:

Beit known that I, WILLIAM WEBsTER, of San Francisco, in the county ofSan Francisco and State of California, have invented an Improved Bungfor Barrels; and I do hereby declare that the following is a full,lclear, and exact description of the same, reference being had to theannexed drawing, and to the letters marked thereon.

My invention relates to an improved bung for barrels, and it consists ina novel combination of a permanent bushing for the barrel with a bungand an improved method of securing the same so that it shall be tight,and at the same time easily removable at any time when necessary.

To more fully illustrate my invention, reference is had to the annexeddrawing, in which Figure l is a sectional elevation, showing the bushand bung in place. Fig. 2 is a perspective view of the bung and nut. vFig. 3 is a bottom view of the bushing, showing the nut.

A is a bush of metal, which is screwed into the openin g made in thebarrel for that purpose. At the bottom or in side end of the bush is aflange, B, which contracts the opening, as shown. Two lugs,C G, projectinto the barrel from this iiange, in aline parallel with the axis of thebushing, for the purpose of locking the bung when in place. The bung Dis made small enough to pass into the bushing, and a leather washer, c,upon its under side rests upon the iiange B when it is in place, andthus makes a tight joint. The upper part ofthe bung is so made as toreceive a key or wrench, for the purpose of turning it when necessary. Ascrew, E, projects from the lower end of the bung, and a peculiar-shapednut, F, fits the screw. This nut is smaller than the opening throughflan ge B for the principal part of its circumference, but is providedwith two lugs, g, at opposite sides,which can only pass through theopening in the bushing by turning the bung to one side.

It will be manifest, then, that when it has been pushed through andturned, so as to be straight again, the lugs g will rest against thelower side of the flange B.

The operation will be as follows: The bush A being screwed into thebarrel, the bung is inserted by turning the nut F until it standsacross, so that the head of the bungwill turn enough to allow the nut topass through the opening` until it is below the fiange B. Then, byturning the bung around, the nut will be drawn up against the bottom ofthe iiange B, the lugs C preventing the nut from turning around.

The lower end of the lever may have ahead to prevent the nut from coming oi'.

If desired, the lugs C may be formed inside the bushing, so that the nutF will be inside ofthe bush, and not project into the barrel.

In this case a square socket may be formed in the top of the bung, whichwill be flush with the top of the bushing. This socket serves to receivea key toloosen the nut when neccssary to take out the bung.

By this construction I ain enabled to make a bung which shall be tight,and at the same time easily removable.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is p The bushing A, with its iiange B and lugsC G, in combination with the bung D, with its screw-spindle E, and thenut F, with lugs g, constructed to operate substantially as and for thepurpose herein described.

In witness whereofl I have hereunto set my hand and seal.
